Application tiled February 15, 1921.

To all wine m it concern:

Be itknown that we, WILLIAM L. Minion, Jr, and BUFORI) F. Mnn'rznn citizens of the United States, residing at ivaynesboro, in the count of Franklin and State of Pennsylvania, ave invented certain new and useful Improvements in a Milk-Bottle Cup, of which the following is a specification.

This invention relates to milk bottle caps and more particularly to an improved closure for mounting in the open top of a milk bottle whereby the bottle will be air tight.

One of the objects of the invention is to provide a milk bottle closure of this characmember 3 will be held ,in the fingers, the

ter which will consist of a sim 1e and inexpensive piece of suitable material shaped to conveniently fit the neck of the bottle and have a convenient finger grip whereby the closure may be readily removed.

Another object of the invention is to provide a closure of this character which will be constructed whereby the finger grip may be utilized as a reinforcing member whereby strength is flVGl'l to the closure disk so that the life of t e same will be increased.

Other objects of the invention will appear upon consideration of the following detail description and accompanying drawings, wherein Figure 1 is a cross section through a portion of a bottle showing the invention ap' plied thereto,

.Figure 2 is a plan. view of the same,

Figure 3 is a perspective view of the device constructed in accordance with my invention. 1

Referring to the drawing by numerals, the bottle neck Fig. 1 is of the usual construction having the usual annular recess whereby a closure member may beplaced in position to close the open end of the bottle. This closure member consists of a piece of cardboard or other suitable material, it being understood that material of any preferred kind may be utilized in constructing the device. The piece consists of a substantially circular disk 1, folded at the center to form a diemetrically extending rib 2 of substantiall T shape which serves as a finger grip in ad dition to a reinforcing member. This member 2 is formed by folding the central portion of the material on lines 5 and 6 as shown to advantage in Figs. 1 and 3 of the drawing thereby forming a substantially wi e strip 3 which when the stopper is pressed .LutO its Bpcclfitatton or letters Patent.

normal position provides a diametrically extending rib having recesses t on each side constitutin linger en gaging means for grasping tie rib. So to ding the strip provides a triple thickness. of material at the center of the stopper increasing the strength of the disk and permitting, the two semi-circular portions of the disk 1 to be folded toward or away from each other so that the disk may be conveniently inserted in the neck of the bottle. The ends'of said T shaped rib engage the inner periphery of the bottle, as shown in Fig. 2.

When the device is in use, the finger grip fingers being inserted in the recesses 4 on opposite sides'thereof and the disk pressed downwardly into position in the recess in the neck of the bottle as shown in Fig. 1 thus causing the neck to be entirely closed. The diametrically extending strip in addition to serving as a finger grip also serves as a rein forcement for the disk so that the life of the disk is materiall increased. Furthermore the relatively wi( e surface of the portion 3 provides a convenient space for receiving and: vertising matter. 1

While the above shows thepreferred embodiment of the invention it will be under provide a circular disc having aflat diametrically extending rib of substantial] -T shape in cross section, the ends of Sci T shae portion engaging the inner periphery of t e bottle.

In testimony whereof, we have aflixcd our signatures in the presence of two witnesses.
